With the announcement of the “imminent liberalization of the two-child policy”, it seems that the whole nation is on the move, both the old and the young. Of course, generally speaking, this is for healthy women, but is this fair? But is it fair? Can women with cancer also enjoy the right to “two children” on an equal footing? In the past, it seemed that women with cancer did not dare to think about it because they were facing the problem of survival, and the problem of reproduction naturally took a back seat. With advances in medicine, is it possible to have both? Recent findings have given hope to women with breast cancer and are nothing short of inspiring. Can women with breast cancer have children after treatment? How soon after treatment can you have children? Does pregnancy increase the chances of breast cancer recurrence? Is it possible to continue treatment during pregnancy? Are babies born after treatment healthy? Can I breastfeed as a normal woman after treatment? The 2011 Royal College of Obstetricians and Gynecologists (RCOG) Guidelines on Breast Cancer and Pregnancy have given us a new understanding of these questions, as well as fresh hope and confidence. Can women with breast cancer have children after treatment? Does pregnancy increase the chance of breast cancer recurrence? Women with breast cancer can have children after treatment, which will neither increase the chance of recurrence of breast cancer nor affect the long-term survival rate of women with breast cancer, and even reduce the relative risk of death, and there is no difference in genetic abnormalities in the offspring and the occurrence of tumors in childhood compared to the offspring born to women who do not have breast cancer. Of course, women who have been diagnosed with advanced (stage 4) metastatic breast cancer are not recommended to continue pregnancy, and there is also a point that requires special attention is the issue of “ovarian function protection” after diagnosis, before chemotherapy and/or endocrine therapy. If you have been diagnosed with breast cancer but still have plans to have children, you should fully communicate with your breast cancer specialist and obstetrician/gynecologist and take measures to protect your ovarian function to avoid loss of fertility after chemotherapy/endocrine treatment. How long can I have children after treatment? How long after treatment is suitable for women with breast cancer to get pregnant? It is generally recommended to be after 3 years, because most of the metastasis and recurrence of breast cancer women occur within 3 years after diagnosis. If you have safely passed the 3 years after diagnosis and treatment, the chances of metastasis and recurrence are greatly reduced, and you can feel relieved to go for childbearing, but of course, it is better to have a routine checkup before you are ready to get pregnant to make sure that there is no recurrence and metastasis before you try to conceive. Is it possible to continue treatment during pregnancy? Is the baby born after treatment healthy? If recurrence is detected during pregnancy, is it possible to continue breast cancer treatment? An international study published in The Lancet Oncology on August 16 shows that women with breast cancer can be treated during pregnancy without an increase in adverse fetal or maternal outcomes, and that there are no major birth defects compared to fetuses whose mothers were not treated with chemotherapy during pregnancy! Just a low birth weight. Of course, doctors in China are conservative compared to others and usually recommend that treatment is not appropriate in the first trimester of pregnancy, and women taking tamoxifen are advised to stop taking the drug for 3 months before becoming pregnant. Can I breastfeed like a normal woman after treatment? Can a woman with breast cancer breastfeed as a normal woman? The healthy side is perfectly fine, while the affected side after breast-conserving surgery + radiotherapy is not suitable for breastfeeding. The above question is about whether it is possible for women to interrupt their breast cancer treatment to complete their childbearing program, which is not common and has not been supported by reliable clinical data so far, therefore, it is not recommended to interrupt the treatment to complete the childbearing program at present. Therefore, it is not recommended to interrupt treatment to complete a fertility program. Thus, women with breast cancer can also embrace the “two-child” spring breeze, and hold the hope of having a child or having another child!
